利用MALDI-TOFMS测定了八种人参皂苷的分子量,并分析了西洋参总皂苷的组成.同时,进行了灵敏度实验,并探讨了基质及碱金属离子的影响,证明该方法灵敏度高,重复性好,结果准确.是测定极性小分子分子量的有效方法.
The molecular weight of eight kinds of ginsenosides was determined by MALDI-TOF MS, and the composition of ginseng saponins was analyzed.At the same time, the sensitivity experiments were carried out and the effects of matrix and alkali metal ions were discussed. The results showed that the method was sensitive and reproducible, Accurate results. Is to determine the polarity of small molecules molecular weight effective method.
